Application Instructions for GFTK VDW 950 StoneProtect Plus 3 In 1

1.Construction Site Requirements

A clean and dust-free, structurally sound, absorbent and dry paved surface which is otherwise ready for jointing; or with jointing that is fully cured and has no residual resin binder on the surface. Ambient and surface temperatures minimum 10 ° C / 50 °F, maximum 26 °C / 80 °F, with dry weather conditions and no rain or heavy dew forecast for at least 24 hours.

2. Tools

Low pressure sprayer, brushes, or rollers; sponges to remove any excess.

3. Application

The areas to be treated should be completely dry, clean and free from any dirt or contaminants that could prevent or reduce penetration. Apply the Xtreme Stone Protect 3-in-1 with a suitable low pressure sprayer, brush, or roller evenly over the surface to saturation, but avoiding any residual ponding or puddling. Remove any excess with a sponge; this is particularly important on surfaces with uneven absorbency, otherwise localized darkening can occur. Avoid splashes on adjacent materials and remove any spillages immediately with a damp cloth. Suitable PPE should be used, including goggles and gloves etc.

4. Curing

Protect area‘s treated with the Xtreme Stone Protect 3-in-1 from moisture and any other dirt or surface contamination for a minimum of 5 hours before access, 24 hours before use (at 20 °C / 68 °F and 65 % relative humidity). When completely dry, the treated paving can also be pointed with the appropriate PHNA jointing compound, if this was not completed before the treatment.
